Gravity / Syphon Fed Septic Fields

Since the new regulations came into force, gravity or syphon tanks and gravity fed septic fields are almost non existent. The code requires an inline filter on all septic tanks which are almost impossible to install without critical failures on a gravity system. Gravity fed septic fields receive all the sewage water (effluent) by being dumped into one area. This part of the field becomes waterlogged and plugged and the effluent migrates slowly along the trenches until it can be displaced. This system is prone to failure on today’s modern homes as the water usage is significantly higher than it was on Grandpa’s 1000 sf farm house.
